Also, try out Noiseware Pro. That's my favorite. Fast, easy to use. There
is also a free version.

When you reduce the effect of noise in a program like photoshop
1. How effective is it in reducing noise? 2. What are the undesireable things it does when noise it reduced? David J Taylor wrote: measekite wrote: [] All of the sample shots I find are ISO80. I would like to see the same shot at ISO 80,200,400. I suggest you borrow a camera from a photo store and take pictures for yourself, as we seem to have established that the camera is basically OK for you. Also be aware that as already mentioned you can reduce the effect of noise in an image with programs like Neat Image, Paint Shop Pro etc. I really wouldn't get hung up on this - if you want low noise from a small sensor camera stick with low ISO, and if you need low noise and high ISO, buy a DSLR.

Anyone know if the Canon S2 shows all of the menu information in the EVF
like the Z5? I like that feature.

I don't know, but I also value that feature on my C-750. Sometimes you just
have to use the EVF in bright sun to set menu items. I think its one of the secret (and overlooked)advantages of having a camera with an EVF over one with an optical viewfinder.

I often shoot theater productions at ISO 400 and get plenty of noise. I
batch run the files through Noiseware Pro and that makes a huge improvement. It subtracts color and luminance noise without reducing sharpness. The adjustments let you determine how smooth you want the noisy areas to be before it starts to look plastic and phoney. I think these noise programs are invaluable with typical digital camera noise.

Ed I'd second what Ed said - although I used to use NeatImage and now use Paint Shop Pro. The programs are very effective reducing noise and retaining sharpness. If you overdo the noise reduction, large areas of the image cam become the same colour, resulting in a sort of "plastic" appearance, which you may have seen in multiple-generation analog video-tape copies.

@newssvr13.news.prodigy.com: When you reduce the effect of noise in a program like photoshop 1. How effective is it in reducing noise? 2. What are the undesireable things it does when noise it reduced? I would say that the effectiveness of noise reduction varies from image to image. For example, if the main subject is reasonably well illuminated, its intrinsic noise levels will likely be low. If the background is darker, then that's where the noise is likely to show up. If the background is out-of-focus, then applying noise reduction to it will not disturb much detail, so the noise reduction will be fairly "invisible" but effective. If the entire image is noisy, then it may fundamentally already have less detail as a result of the noise. Hence, applying noise reduction may reduce the details even further, and also affect the tonal transitions, to make the end result look a bit "plasticky". To some degree, the undesirable effects of noise reduction are a subjective assessment that depends on the print size and the image quality desired by the photographer. It may be instructive to investigate the effects of noise reduction on images for yourself. That way you can readily gain some first hand experience. There are a number of demo or freeware versions of noise reduction software that can be installed on your computer. Then, it is possible to download some images from the digicam review sites that have specifically been taken with varying ISO values and therefore varying degrees of noise present. Apply the the noise reduction and see what you get, and you should then be able to reach a judgement as to how important noise might be for your purposes. Keep in mind that using a ZLR at ISO 200 or ISO 400 will result in images that are quite a bit noisier than those from a DSLR at the same or even higher ISOs. -- Witold. |

m: Anyone know if the Canon S2 shows all of the menu information in the EVF like the Z5? I like that feature. I would suggest that you take a look at some reviews of the Canon S1. That camera does show all the menu information in the EVF, and I imagine that the Canon S2 will be quite similar in that regard. I am looking forward to reading the reviews of the Canon S2 IS when they are published; it seems like a nice camera in its market slot. -- Witold. |
